explain why, I can connect back up, its very easy and quick. So if you put a breather on the valve cover instead of a PCV this must be bad as well?
By itself no it's not bad, so long as you service it at regular intervals. But When you floor it the blow-by gasses will be greater than your atmospheric dump can pass, so now they will pass out of the engine thru that breather. The gasses will be laden with oil,and/or oil vapors that the crank is furiously churning up. The breather will do the best it can to separate the oil, but it not likely to get it all, and so the general area around it will become increasingly messy.explain why, I can connect back up, its very easy and quick.

Which valves are those?Ok this is what PCV does to a direct injected engines intake valves, you think its pretty good eh?
With my mopar 360 I am connecting the PCV up for sure, it will have no issues!

I agree with both statements.I have read, no experience with, GDI cars having carbon build up on the valves. Same articles have attributed that to improper oil use, and extended oil change intervals. Synthetic oil is supposed to greatly reduce the build up, as does more frequent oil changes.
I am still of the opinion, that in cars of our generation Fs, Js, and Ms, that a working PCV system is a pretty major benefit.
